Create: Mortar
If you have ever stacked half a dozen Create add-ons into a single modpack, you already know the pain: machines that should accept each other's items simply refuse to cooperate, and recipes silently break because the tags they rely on were never defined. Create: Mortar exists to solve exactly that problem. It is a lightweight compatibility patch that fills in the missing tags and corrects recipes so that several popular Create expansions finally play nicely together.
What Create: Mortar Actually Does
Create: Mortar is not a content mod in the traditional sense. It does not add new machines, new ores, or a fresh tech tree. Instead, it acts as a bridge between mods that were designed in isolation. When two add-ons use different tag names for the same material, or when one expects an item that another never registers, Mortar steps in and harmonizes the data.
The result is a modpack where cross-mod automation works the way you always assumed it should. Ingots, dusts, and intermediate components flow between systems without you having to hand-craft workarounds or edit JSON files at midnight.
Supported Add-ons
The add-on focuses on a specific set of Create expansions that are frequently combined in kitchen-sink packs. Compatibility currently covers:
- Create: Big Cannons
- The Factory Must Grow
- Crafts & Additions
- Steam 'n' Rails
- Dreams & Desires
- Create: Deco
- Create: Diesel Generators (added in v0.2.2)
- Create: Molten Metals (added in v0.2.0)
Each of these mods brings its own materials and processing chains, and Mortar makes sure the overlapping parts share a common language. That means fewer broken recipes in JEI and more automation setups that just work.
Version Support and Loaders
Create: Mortar is built for modern Minecraft releases and targets the Forge loader, which is the platform most Create add-ons are developed against. Because Create itself has moved through several major versions, you should always match the Mortar build to your Create version and your Minecraft version before installing. Mixing a patch designed for one Create release with a different one is the fastest way to generate a crash log.
If you are running a large pack, check that every supported add-on is present at a compatible version. Mortar only fixes interactions between mods that are actually installed, so a missing dependency will simply leave those recipes untouched.
How to Install Create: Mortar
Installation follows the standard Forge mod workflow, so anyone who has added a mod before will feel at home.
- Confirm your Minecraft version and your Create version.
- Download the matching Create: Mortar file for Forge.
- Place the .jar into your mods folder.
- Make sure every supported add-on is installed at a compatible version.
- Launch the game and check JEI for recipes that previously failed to appear.
For server owners, the mod must be present on both client and server, since it changes recipe and tag data. A client-only install will not resolve anything on a multiplayer world.
If you would rather skip the manual file juggling, the foxygame.net launcher handles the whole process for you: it detects your installed Create version and pulls the correct Create: Mortar build automatically, so tags and recipes stay in sync after every update without you touching a single config file.
Common Installation Problems
The most frequent issue is a version mismatch between Mortar and Create. If the game crashes during startup with a data pack or tag error, that is almost always the cause. The second most common problem is a missing supported add-on, which leaves some recipes unfixed but will not crash the game. Finally, remember that adding Mortar to an existing world is generally safe, but removing it later can leave recipes referencing tags that no longer exist.
Why It Belongs in Your Modpack
Create: Mortar is the kind of mod you install once and then forget about, which is the highest compliment a compatibility patch can receive. It does not compete for attention with the add-ons it supports; it simply removes the friction that makes combining them frustrating. For players who enjoy building sprawling factories that mix steam, diesel, and molten metal processing, that friction is often the difference between a working pack and an abandoned one.
Whether you are assembling a fresh modpack or repairing an existing one, adding Create: Mortar is a small step that pays off every time you place a machine and find that it accepts exactly the item you expected. Download Create: Mortar for Minecraft, verify your versions, and let your factory grow without the usual compatibility headaches.
